Abstract

The cross-member consists of upper (16) and lower transverse beams connected to lower lengthwise members carrying the wheel housings, with a front wall (20) of the lower beam forming, together with a guide wall (21) and a bottom wall (22), an assembly and fixing channel (30). The upper transverse beam fits into the assembly channel (30), while the bottom wall (22) forms a thrust base for the cross-member assembly on supports (31) to which the front wheel suspension arms are attached. The lower beam is made with a lengthwise slideway for fixings, e.g. nuts (33) engaging with the ends of bolts (35), while the rear wall of the upper beam (16) fits against a panel (12) which acts as a spacer for shock absorber side members.

Description

L'invention concerne une traverse de châssis de véhicule automobile qui limite longitudinalement un compartiment moteur et qui est formée par une poutre transversale supérieure et par une poutre transversale inférieure respectivement reliées à deux longerons porteurs des zones d'appui des passages de roues.The invention relates to a cross member of a motor vehicle chassis which longitudinally limits an engine compartment and which is formed by a upper transverse beam and by a lower transverse beam respectively connected to two supporting beams of the support zones of the wheel arches.

La publication FR-A-2503652 décrit une traverse d'extrémité de carrosserie qui permet le montage d'un pare-chocs. Dans cette réalisation la traverse transmet des efforts de compression aux longerons. Toutefois lorsque le motopropulseur est disposé à l'avant du véhicule, le recul accidentel de celui-ci lors des collisions n'est plus limité longitudinalement.Publication FR-A-2503652 describes a body end cross member which allows the mounting of a bumper. In this realization the cross transmits compression forces to the side members. However when the powertrain is located at the front of the vehicle, accidental recoil of it during collisions is no longer limited longitudinally.

La déformation concomitante du tablier n'est pas sans risques pour le passager et/ou du conducteur du véhicule.The concomitant deformation of the deck is not without risks for the passenger and / or driver of the vehicle.

La publication FR-A-1296074 décrit un cadre rigide et un plancher de véhicule limité par le contour intérieur de ce cadre.The publication FR-A-1296074 describes a rigid frame and a floor of vehicle limited by the interior outline of this frame.

Le cadre est dans ce cas constitué par des longerons et par des traverses parmi lesquelles la traverse antérieure est constituée par un ou plusieurs éléments assemblés en métal ou alliage léger.The frame is in this case constituted by longitudinal members and by crosspieces among which the front crosspiece is constituted by one or more elements assembled in metal or light alloy.

On constate que le tronçon avant des longerons orienté d'avant en arrière est souvent coudé vers le bas dans la zone du tablier pour se prolonger vers l'arrière dans la zone du plancher du véhicule. Chaque longeron présente alors dans la zone de son coude un grand moment de flexion qui ne peut être compensé aisément sans une structure de châssis adaptée. Lorsqu'un effort longitudinal s'exerce sur ce longeron, le plancher a une tendance à fléchir en absorbant une partie négligeable de l'énergie due aux chocs. It can be seen that the front section of the side members oriented from front to back is often bent down in the apron area to extend towards the rear in the vehicle floor area. Each spar has then in the area of his elbow a great bending moment which cannot be easily compensated without a suitable chassis structure. When an effort longitudinal is exerted on this spar, the floor tends to flex in absorbing a negligible part of the energy due to shocks.

On sait par ailleurs que la sécurité des occupants du véhicule est sensiblement améliorée par l'agencement de parois transversales résistantes aux efforts longitudinaux.We also know that the safety of vehicle occupants is significantly improved by the arrangement of transverse stress-resistant walls longitudinal.

L'invention a donc pour objet une traverse de châssis réalisée de manière à ce que les forces s'exerçant dans le sens longitudinal, par exemple en cas de choc accidentel à l'avant, soient absorbées sans risquer une déformation du plancher du véhicule.The subject of the invention is therefore a chassis crossmember made so that that the forces acting in the longitudinal direction, for example in the event of accidental impact at the front, are absorbed without risking deformation of the vehicle floor.

L'invention a encore pour objet une traverse de châssis en deux parties assemblées de manière favorable, d'un poids aussi faible que possible, dans le but de maintenir l'efficacité de la traverse en fonction des masses rendues mobiles lors des collisions et susceptibles de générer des efforts de déformation sur le tablier.The subject of the invention is also a cross-member in two parts favorably assembled, as light as possible, in the goal of maintaining the efficiency of the cross member according to the masses returned mobile in collisions and likely to generate deformation on the apron.

Selon l'invention, la paroi avant de la poutre inférieure de la traverse, délimite avec une paroi de guidage et une paroi de fond de ladite poutre inférieure, une rainure de montage de la poutre supérieure, et ladite paroi de fond constitue la base d'appui de l'ensemble de la traverse, sur les supports de fixation d'éléments de suspension des roues avant du véhicule.According to the invention, the front wall of the lower beam of the cross member delimits with a guide wall and a bottom wall of said lower beam, a mounting groove for the upper beam, and said bottom wall constitutes the support base for the entire cross member, on the fixing of suspension elements of the front wheels of the vehicle.

La traverse ainsi réalisée présente l'avantage de pouvoir être dimensionnée en fonction des organes moteurs et de transmission supportés par le châssis. Le montage séparé de la traverse sera par ailleurs particulièrement pratique et évitera le transfert de l'ensemble du châssis le long de la chaíne de montage.The cross member thus produced has the advantage of being able to be dimensioned in function of the drive and transmission components supported by the chassis. The separate mounting of the cross member will also be particularly practical and will avoid the transfer of the whole chassis along the assembly line.

D'autres caractéristiques et avantages de l'invention apparaítront à la lecture d'un exemple de réalisation de la traverse de châssis en référence aux dessins annexés dans lesquels :

  • la figure 1 est une vue en perspective de l'avant du châssis montrant l'emplacement de la traverse,
  • la figure 2 est une vue en perspective du montage de la traverse du châssis,
  • la figure 3 est une section transversale III-III du montage représenté à la figure 2,
  • la figure 4 est une section médiane IV-IV du montage représenté à la figure 2.
Other characteristics and advantages of the invention will appear on reading an embodiment of the chassis crossmember with reference to the appended drawings in which:
  • FIG. 1 is a perspective view of the front of the chassis showing the location of the cross-member,
  • FIG. 2 is a perspective view of the mounting of the cross member of the chassis,
  • FIG. 3 is a cross section III-III of the assembly shown in FIG. 2,
  • FIG. 4 is a middle section IV-IV of the assembly shown in FIG. 2.

Tel que représenté à la figure 1, le châssis proprement dit, possède deux longerons avant supérieurs 1 entretoisés par une traverse 11 et qui se prolongent vers l'arrière par deux longerons inférieurs 2 respectivement assemblés à des poutres latérales 3. Les longerons inférieurs 2 et les poutres 3 sont par ailleurs entretoisés par des appuis de raccordement 4 aux passages de roues 5 du véhicule eux-mêmes en appui sur lesdits longerons inférieurs 2.As shown in Figure 1, the chassis itself has two upper front side members 1 braced by a cross member 11 and which extend rearwards by two lower beams 2 respectively assembled to side beams 3. The lower beams 2 and the beams 3 are also braced by connecting supports 4 to the passages wheels 5 of the vehicle themselves resting on said lower beams 2.

Les longerons inférieurs 2 sont recouverts par une tôle de plancher 6 rigidifiée en sa zone médiane par un tunnel longitudinal central 7. Les poutres latérales 3 sont surmontées par des montants latéraux 8 auxquels sont fixées des parois latérales 9 de maintien d'un logement 10 d'amortisseur.The lower beams 2 are covered by a floor plate 6 stiffened in its middle zone by a central longitudinal tunnel 7. The beams lateral 3 are surmounted by lateral uprights 8 to which are fixed side walls 9 for holding a damper housing 10.

Les parois latérales 9 sont également entretoisées par un tablier 12.The side walls 9 are also braced by an apron 12.

Le tablier 12 s'étend de la sorte verticalement entre les parois 9 et possède un tronçon de paroi oblique 13 que prolonge vers le bas un tronçon de paroi vertical 14. Le tronçon de paroi vertical 14 est accolé ainsi que cela est montré aux figures 3 et 4 à la traverse de châssis 15. Cette dernière est formée par une poutre transversale supérieure 16 et par une poutre transversale inférieure 17.The apron 12 thus extends vertically between the walls 9 and has a oblique wall section 13 extended downwards by a wall section vertical 14. The vertical wall section 14 is joined as is shown in Figures 3 and 4 to the chassis cross member 15. The latter is formed by an upper transverse beam 16 and by a beam lower cross 17.

La poutre inférieure 17 est fractionnée en deux parties 17g et 17d respectivement en appui par l'intermédiaire de plaques de fermeture 18 sur les flancs du tunnel 7.The lower beam 17 is split into two parts 17g and 17d respectively in support by means of closure plates 18 on the sides of the tunnel 7.

Selon l'invention la paroi avant 20 de la poutre inférieure 17 est écartée d'une paroi de guidage 21 et délimite avec une paroi de fond 22, une rainure de montage 30 et d'encastrement du tenon 40 de la poutre supérieure 16. According to the invention the front wall 20 of the lower beam 17 is spaced apart guide wall 21 and delimits with a bottom wall 22, a groove of mounting 30 and mounting of the pin 40 of the upper beam 16.

Dans le but de faciliter le montage simultané des poutres 16, 17 sur le véhicule, la paroi de fond 22 constitue la base d'appui de la traverse 15 sur les supports de fixation 31 des éléments de suspension incluant notamment les triangles de suspension 41 des roues avant du véhicule.In order to facilitate the simultaneous mounting of the beams 16, 17 on the vehicle, the bottom wall 22 constitutes the support base for the cross member 15 on the fixing supports 31 of the suspension elements including in particular the suspension triangles 41 of the front wheels of the vehicle.

La fixation des parties 17g et 17d de la poutre inférieure 17 sur le support correspondant 31 s'opère au travers de la paroi de fond 22 dans une glissière longitudinale 32 de réception d'écrous de fixation 33. Les écrous 33 sont introduits dans la glissière 32 au travers d'une boutonnière 34 et reçoivent des vis d'assemblage 35 respectivement guidées entre deux parois internes de rigidification 36 de la poutre 17.The fixing of the parts 17g and 17d of the lower beam 17 on the support corresponding 31 operates through the bottom wall 22 in a slide longitudinal 32 for receiving fixing nuts 33. The nuts 33 are introduced into the slide 32 through a buttonhole 34 and receive assembly screws 35 respectively guided between two internal walls of stiffening 36 of the beam 17.

Selon une autre caractéristique de la traverse 15, la rainure de montage 30 de la poutre inférieure 17 assure également l'immobilisation verticale et le positionnement de la poutre supérieure 16 dont une paroi arrière est en appui sur le tablier 12 au niveau du tronçon de paroi vertical 14.According to another characteristic of the crosspiece 15, the mounting groove 30 of the lower beam 17 also ensures the vertical immobilization and the positioning of the upper beam 16 with a rear wall in support on the apron 12 at the vertical wall section 14.

Ainsi que cela est montré à la figure 3 la poutre supérieure 16 possède une structure alvéolaire qui lui confère notamment une résistance aux efforts de déformation, suffisante pour empêcher des flexions longitudinales non désirées d'avant en arrière de ladite poutre 16.As shown in Figure 3 the upper beam 16 has a cellular structure which in particular gives it resistance to the forces of deformation, sufficient to prevent non-longitudinal bending desired from front to back of said beam 16.

Dans le but d'immobiliser simultanément les constituants de la traverse de châssis par rapport aux flancs des longerons latéraux inférieurs 2, les poutres 16, 17 sont en contact d'assemblage avec des plaques 37g, 37d dont la face extérieure constitue la zone d'appui et de fixation des longerons 2.In order to simultaneously immobilize the constituents of the sleeper chassis relative to the sides of the lower side rails 2, the beams 16, 17 are in assembly contact with plates 37g, 37d whose face outside constitutes the support and fixing area of the side members 2.

Par ailleurs, et en référence à la figure 3, la position correcte de la poutre 16 par rapport à la poutre inférieure 17 est réalisée par une butée de positionnement vertical 38 localisée à la racine du tenon de montage 40 de la poutre 16 dans la rainure 30.Furthermore, and with reference to FIG. 3, the correct position of the beam 16 relative to the lower beam 17 is produced by a stop of vertical positioning 38 located at the root of the mounting pin 40 of the beam 16 in groove 30.
